To all 'iv/iam it 11mg/ con-cern:

y Be it knownthatl, FRANK J. Dnrn\n,`a citizen of the United States, and residing at Detroit, county ot lVayne, State of Michigan,` have invented certain new and usefulImprovements in Radiator Covers, ot

i a so-called i hood or cover over the` sightly.

which the following is a specilication. y

`The present invention relates to inotor vehicle radiators `and more particularly to' means tor reducing the cooling etlect tl'iereoit. During the winter it iscustoniary to use radiatorl `or hood and radiator together, for the purpose oi offsetting the greater coolingI eilect that would otherwise result from the low temperatures oi the atmosphere. Such covers are more or less clumsy and unside oit the radiator or hood they are er;- posed to the weather and soon beconie shabby in appearance.

The present invention aiins to reniedy the above and other detects of the covers heretofore used, and to these ends consists in the` provision oit' heat insulating material `between the core and shell of the radiator.

The objects and novel features of the invention will be apparent Jfrom the descrip-- tion taken in connection with the drawings in which Figure 1 is a perspective view olf a radiator, insulated in accordance with the present invention, sonic of the parts beingbroken away to clearlyshow the insulation;

Figure 2 is a perspective view of a radiator shell;

Figure 3 is a jtront elevation ot'a curtain adapted to be secured to the edges of the insulation and close the usual air aperture in the shell; i

Figure 4: is an enlarged sectional elevation, taken substantially on the line 1 -l of Fig` ure 1; and

Figure 5 is an enlarged sectional plan taken lsubstantially on the line 5 of Fig ure 1. i

Reterrin to the drawings it` will be seen that they i lustrate a radiator oft usual construction, that is, one having` a core indicated in general by the reference numeral and a removable shell 11 disposed around the core. Usually, the shell is secured to the core by having its rear` flange l2 bolted Furthermore, beingon the out` `an aperture 15 for the air to pass through the radiator. If desired, the edge of the flange 11lbounding the aperture 15 may be iorrned with a bead 16.

According to the present invention,` in order to keep the temperature 0i.' the fluid within the radiator as nearly constant as possible during cold weather and also in order to o'lset the excessive cooling` action due to the low temperatures obtaining in winter, heat insulating inaterial 17 is disposed around the periphery of the core between the core and the shell. Preferably, this material is in the form of a blanket 17 whichis shaped to the contour of the radiator core and at the front of the core is provided with an overhanging portion 1S. Preferably, this portion 18 projects' slightly within the bead 1G ot the shell, thereby pro viding `flap or lip 19 to which may be secured a curtain 20 for the purpose of regulating the size of the opening` 15.

As shown in the drawings the blanket 17 inay consist of two outside layers of fabric 21 with an interposed layer 22 ol' ielt or other suitable material. The layers are secured together in any suitable manner as by ineans of the stitching 23.

i l? rom the foregoing description it will be seen that the blanket 17 may be easily put on or removed from the core after the shell l1 has been taken oil, so that the blanket inay be placed on the core at the beginning ot winter and removed at the end oit' the cold period without the services ot a skilled mechanic.

The curtain 20 is preferably secured to the flap 19 by means such as glove fasteners 24, and may be of any suitable construction but preferably is inade up in sections, as shown in Figure 3. rlhus the curtain may be formed with the two parallel horizontally eX- tending thin or flexible portions 25 and 26 whereby the upper section A may be turned down about the flexible or hinge portion 25 and secured flat against the section B by the glove 'fasteners Q7. In this manner about one-third of the usual aperture 15 is open and the remainder covered by the blanket. It' it is desired to have a larger air passage through the radiator then the two sections A, B, may be turned down asa unit about the hinge portion Q6 and secured against the lower section 3 of the curtain by the fasteners 28. Finally, if it is desired to have the entire opening 15 free, the curtain may be entirely removed by unclasping the glove fasteners 24. Wlhile a curtain ot' the construction just described is preferred, the curtain by itself is not included in the presentinvention but is described and claimed in a. (3o-pending vapplication Serial Number 269,428, filed January B, 1919.

Although an embodiment `of the invention has been described in detail it, is to be understood that the invention is vnot thus limited but includes vmoditicationsand changes which come within the scope of the appended claims. K Y

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is l. A. motor vehicle radiator comprising in combination, a core, a removable shell surrounding the core and having an opening for air to pass through the core, a blanket disposed between said core and shell and projecting slightly beyond the edge of the shell bounding said opening, anda curtain Closing said opening and detachably secured to the projecting portion of the blanket.

2. The combination with the core and surrounding shell of a motor vehicle radiator` of heat insulatin v material disposed between said core and siell, a curtain disposed to close the air opening;lr in the front of the radiator, and means to detachably fasten said curtain to said material.

In testimony' whereof I affix my signature.
